how to change the dist-folder path in angular-cli after 'ng build'

The more current way of this is to update the outDir property in angular.json(called .angular-cli.json in old Angular CLI versions).

The ng build command argument --output-path (or -op for short) is still supported also, which can be useful if you want multiple values, you can save them in your package.json as npm scripts.

Beware: The .angular-cli.json property is NOT called output-path like the currently-accepted answer by @cwill747 says. That's the ng build argument only.

It's called outDir as mentioned above, and it's a under the apps property.

For Angular 6+ things have changed a little.

Define where ng build generates app files

Cli setup is now done in angular.json (replaced .angular-cli.json) in your workspace root directory. The output path in default angular.json should look like this (irrelevant lines removed):

{
  "projects": {
    "my-app-name": {
    "architect": {
      "options": {
         "outputPath": "dist/my-app-name",

Obviously, this will generate your app in WORKSPACE/dist/my-app-name. Modify outputPath if you prefer another directory.

You can overwrite the output path using command line arguments (e.g. for CI jobs):

ng build -op dist/example
ng build --output-path=dist/example

S.a. https://angular.io/cli/build

Hosting angular app in subdirectory

Setting the output path, will tell angular where to place the "compiled" files but however you change the output path, when running the app, angular will still assume that the app is hosted in the webserver's document root.

To make it work in a sub directory, you'll have to set the base href.

In angular.json:

{
  "projects": {
    "my-app-name": {
    "architect": {
      "options": {
         "baseHref": "/my-folder/",

Cli:

ng build --base-href=/my-folder/

If you don't know where the app will be hosted on build time, you can change base tag in generated index.html.

Here's an example how we do it in our docker container:

entrypoint.sh

if [ -n "${BASE_PATH}" ]
then
  files=( $(find . -name "index.html") )
  cp -n "${files[0]}" "${files[0]}.org"
  cp "${files[0]}.org" "${files[0]}"
  sed -i "s*<base href=\"/\">*<base href=\"${BASE_PATH}\">*g" "${files[0]}"
fi

You can update the output folder in .angular-cli.json:

"outDir": "./location/toYour/dist"

You can use the CLI too, like:

ng build -prod --output-path=production

# or

ng serve --output-path=devroot
